2-in-1 laptop battery replacement

The ARCTIC L18C4PF3 is a 45Wh 15.36V Li-ion battery designed for compatible Lenovo IdeaPad Flex and C340 or S540 14-inch convertible models. It includes installation tools for user fitting. This product suits owners of those specific 2-in-1 devices needing a direct power source replacement.

Replaces multiple OEM part numbers

This unit replaces part numbers L18M4PF3, L18M4PF4, L18C4PF4 and 5B10T09077, 5B10T09079, 5B10T09080, 5B10T09081, 5B10W67194, 5B10W67221, 5B10W67415, 5B10W67417. The jump is worth it when the original battery no longer holds sufficient charge or fails to be recognised by the system.

Sustained operation after conditioning

If the battery is not recognised initially, reinstall and ensure the interface is fully connected. Discharge to 5%, then charge and cycle three to four times to wake up the new cell. This conditioning process establishes stable sustained output for regular daily use.

Questions about this item

Does the L18C4PF3 battery fit a Lenovo IdeaPad Flex 14 2-in-1 with part number L18M4PF4?

Yes, the L18C4PF3 replaces part numbers L18M4PF4, L18M4PF3, L18C4PF4, 5B10T09077, 5B10T09080, 5B10W67417, 5B10W67415, 5B10W67221, 5B10T09081, 5B10T09079 and 5B10W67194.

The tips mention the interface must be fully connected — which step do people miss during installation?

After placing the battery, press the connector firmly until it clicks; a loose connection is the most common reason the new battery is not recognised on first boot.

How should I condition the 45Wh Li-ion battery after fitting it?

Discharge it to 5 %, then charge fully and repeat the cycle three to four times to wake up the new cells.
